BB has made his mistakes, for sure. But, he built a 20 year juggernaut with the belief that tier 2 needed to be as close to tier 1 as possible. Didn't care about flash. Found players that fit the system and with the team.
A lot of the guys he brought in were not all-pros, or had been written off. Dillon, Harrison come to mind. So do guys like Patten, Givens, Stallworth and a few more. They fit HERE. TB did make it easier, but it is still an accomplishment.
Now he's had a taste of the darker side, and needs to adjust. It's not surprising that he went all Defense on us - that is his forte. If we could bring in an OC who is on the same page philosophically, and has a strong presence, I can see a big turnaround in a year or two.
A major shake up in the rest of the staff - to include Player Personnel Director and some position coaches - yes. Stronger position experts are needed.
Bingo needs to go - awesome player with no quit, not so much in the coaching role. Klemm - not sure, he does deserve some better ingredients to cook with. Generic "NFL TACKLE", one of which is past the expiration date (along with center) makes for a pretty poor meal. At least get the guy some HEB branded condiments or something.
With all the talent on D, and what I see as good coaches, just amp up the heat a bit. Until the O can produce consistently, the bend-no-break mantra isn't working as well. Turn some of those guys loose more often.
